Rational Numbers Sets And Subsets. You get the entire set of real numbers. A set is a collection of objects or elements, grouped in the curly braces, such as {a,b,c,d}.
The student is expected to extend previous knowledge of sets and subsets using a visual representation to describe relationships between sets of rational numbers. The whole numbers are a subset of the rational numbers. The tree diagram represents the relationships bebween the 4/14 sets and subsets of rational numbers.
Surprisingly, this is not the case.
The venn diagram shows the different types of numbers as subsets of the rational numbers set. The tree diagram represents the relationships bebween the 4/14 sets and subsets of rational numbers. There are no subsets of i but n ⊂ w ⊂ z. Other sets we can take an existing set symbol and place in the top right corner:
